Disadvantages: small memory, low resolution, small ringtone, easy to crash, and slow running of multiple programs.
It should be noted that due to the influence of operators, the most important function of BlackBerry, the ——pushmail function, cannot be effectively supported.
Why use a blackberry?
1. Blackberry signal is the best in the world. She is a global smart phone designed for global business roaming, so the signal compatibility of all countries is very good. No, the 4-band network (850/900/1800/1900) is 20-30% stronger than Nokia, which claims to have the best signal, but its transmission power (radiation) is only 2/3( 0.86w/kg), which is far lower than the standards of developed countries in Europe and America (the United States Blackberry is indeed an excellent choice in terms of call quality and low radiation.
2. Practical function, simple and comprehensive. No matter which brand of mobile phone you usually see, there are many functions that may never be used, but many commonly used functions are designed roughly and simply. This is the beauty of Blackberry, which has few functions, but not a little. He has absolutely possessed the functions that users may use, and each function has been repeatedly researched and designed, which is quite user-friendly and convenient. Don't worry if the function you need is not available in the original factory. As a smart phone, Blackberry has high hardware configuration and excellent expansibility, and can basically be installed on the machine. All JAVA/Cod software at home and abroad, such as QQ, MSN, Great Wisdom, Kingsoft, etc. Basically, you can install it later (that is to say, there are countless BlackBerry software, so it is convenient to install it later when you think about it).
3. Excellent technology determines the durability of BlackBerry. No matter at home or abroad, no one in the industry will deny its Excellence and hardware technology.
Exquisite, every detail, from keys to chips, even outsiders can know how well made. According to rough statistics, BlackBerry should be the second-to-last mobile phone in repair rate after Sharp.
4. High-definition large-size screen 8-series BlackBerry (including 7 105T 7 130) allows us to see a clearer QVGA screen than 260,000. Don't use parameters to measure him, you will fall in love with him at first sight, and you will never lose to Samsung's16 million color screen. In 2004, the 72.77 series, whose TFT liquid crystal without front panel did not reflect light in direct sunlight, was one of the technologies that sensationalized the world at that time, and then the first-generation practical HD 65K color 320*260 screen of the 7 1 series once again broke the limit (compared with the domestic 260,000, those even failed to compare with the 7 1, mainly because the domestic indicators were too wet.
5. World-renowned humanized design The humanized design of BlackBerry is world-famous. RIM will design humanized mobile phones for each type of customers, such as the German version of the BlackBerry, which is in line with German habits. YZ/AZ inversion, amazing automatic lighting/backlight design, automatic switching of GSM/GPRS/EDGE network, BlackBerry keys specially designed for young people (8-series trackball system), and side wheel+full keyboard input symbolizing BlackBerry.
6. Blackberry Java software supports BlackBerry as a smart phone with many softwares. It is also one of the few smart phones that can support the self-compiling software of the highest computer language assembly language. It can be seen that its function is close to that of a computer.
Seven. Rare network, it is the first time to try to have a network called EDGE abroad, that is, mobile broadband network (GPRS enhanced network). In fact, this network has also been opened in China. GPRS traffic is not only charged, but also not many mobile phones support EDGE, so an excellent network is idle. Blackberry will automatically switch between GSM/GPRS/EDGE networks without setting, so do you want to be the first person to eat crabs?
Eight. Qwerty+SureType typing speed is frightening. Blackberry was the first company in the world to use Qwerty full keyboard, and later developed 7 1 8 1 series mini full keyboard with reference to Qwerty technology. Needless to say, the typing speed itself is faster than ordinary mobile phones, and BlackBerry's patented SureType Lenovo input method makes BlackBerry even more powerful. With SureType blackberry, when you input Chinese or English, users only need to type a whole sentence directly, and it will automatically spell out related phrases or words for you (similar to Microsoft Pinyin Input Method), which can be easily realized for slightly skilled users who use 65,438+000 Chinese characters per minute. This is by no means nonsense
Remarks: Many people may think that BlackBerry is not so amazing in terms of technical indicators, but don't forget that BlackBerry uses internationally standardized indicators, and most of them are useless in China. This phenomenon does not only appear on brand-name machines. Big-name machines never say that they are 260,000 colors in large-scale advertisements, only that they are high-definition, because they are afraid that once the relevant industry standards are introduced, it will be more troublesome. In fact, there are very few screens with 260,000 colors in China, and the best screen now is 65438.
